What's Wrong?

Context: I have a Surface 7 ARM laptop and latest Windows updates, Powershell.

While I'm not able to install Claude code using Powershell (the claude.exe is not dropped in C:\Users\magatti\.local\bin\claude.exe) I read about multiple issues and workarounds and none of them unblocks, the issue still persists.

Then I switched over to use cmd as documented in the claude code setup steps and I found a bug which blocks the installation. See repro steps.

It seems that if I download the cmd file and run it locally it works, but if I use the one line command it doesn't.

Thanks

What Should Happen?

The setup steps documented on this page should work.

https://code.claude.com/docs/en/quickstart#step-1:-install-claude-code

curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd

Error Messages/Logs

I'd be happy to know how to get some logs, better error messages during the install process.
